The many aspects of fixed another equipment that electronic equipment 100 is attached to by means of equipment attachment features part 108.In this way,
Overall attachment between another described equipment and electronic equipment 100 can be than being attached separately through the first attachment features part 108
It is stronger.Therefore, and equally without loss of generality, the second attachment features part 110 is referred to below as fixed attachment features part 110.
Although being not explicitly shown, it should be understood that the various magnetic attachment features parts of magnetic attachment system can be positioned in shell 102
Any suitable position.For example, magnetic attachment features part can be positioned at the inner bottom surface of shell 102 or the side along shell 102
102c and 102d.
As shown in fig. 6, equipment attachment features part 108 and fixed attachment features part 110 respectively may include one or more
Magnetic cell.In one example, equipment attachment features part 108 may include that magnetic each other can interact in order to provide magnetic field 112
Multiple magnetic cells of (illustrating only part of it).In other words, the attribute (shape, field strength etc.) in magnetic field 112 can be based on by every
The reciprocation in the magnetic field that a magnetic cell generates.In this way it is possible to by arranging the attribute of each magnetic cell (that is, physics
Layout, relative size and composition magnetic pole) the simple attribute for changing magnetic field 112.For example, each magnetic cell can have difference greatly
It is small, and can be arranged along axis.In this way, the magnetic attribute of each of multiple magnetic cells can play work together
With to establish total attribute in magnetic field 112.
In some cases, can be enhanced by using magnetic shunt path (not shown) for equipment attachment features part 108 and another
The a part in the magnetic field 112 of the magnetic attachment between one equipment.Magnetic shunt path can be formed by the magnetic active material of such as steel or iron, and
And it can be placed on so that the magnetic field line that direction originally can deviate attachment area is at least partly redirected to the position of attachment area
It sets.The redirection of magnetic field line can have the effect for increasing the average flux density in attachment area.
Equipment attachment features part 108 can operate in active state and inactive state.In inactive state, magnetic flux is close
Spend B112Magnetic flux density threshold value B can be equal to or over inside 102 outer surface of shell rather than except itthreshold.Change speech
It, the magnetic flux density B in magnetic field 112112It is less than magnetic flux density threshold value B in the outer surface of shell 102threshold.Magnetic flux density threshold
Value BthresholdIndicate such flux value, under the value, magnetosensitive equipment (magnetic stripe on such as credit card) can keep big
Body is unaffected.In addition, in the exterior domain of electronic equipment 100 magnetic active material (such as steel) there are itself will not trigger equipment
Attachment features part 108 is changed into active state from inactive state.
As described above, when equipment attachment features part 108 is not activated, the outer surface of the side 102a of shell 102
The magnetic flux density B in magnetic field 112112Less than magnetic flux density threshold value Bthreshold.More specifically, for equipment attachment features part 108,
Magnetic flux density B112The function that can be used as the distance x apart from magnetic cell changes (that is, B=B112(x)).Therefore, when equipment is attached
When feature 112 is in inactive, magnetic flux density B112(x) it can satisfy equation (1).
B112(x=xo+t)<BthresholdEquation (1)
Wherein t is thickness of the shell 102 at the 102a of side, and
x0It is the distance inside the 102a of side to magnetic cell.
When equipment attachment features part 108 is in it is inactive when, any magnetic flux except electronic equipment 100 near zone is let out
Leakage is (that is, B112(x>xo+ t)) it is sufficiently low, so that the magnetosensitive equipment near zone is less likely to be adversely affected.However, answering
When note that even if magnetic field 112 can have the flux value B for meeting equation (1) in inactive state112(x=xo+ t), and
Still it is high enough to interact with relative to it close to the magnetic field of another equipment of placement.In this way, even if meet etc.
Formula (1), the other appropriately configured magnetic attachment features parts that can be used in another equipment carry out activation equipment magnetic attachment features part
108。
The attribute in magnetic field 112 can include at least field strength, magnetic polarity etc..The attribute in magnetic field 112 can be based on being included in magnetic
The synthesis in the magnetic field of each magnetic cell in attachment features part 108.Combination field can be formed in polymerization magnetic field 112.For example, magnetic
Element can be arranged in this way, so that the combination in corresponding magnetic field leads to the magnetic with desired magnetic field properties (such as field strength)
Field 112.For example, a kind of combination of arrangement of magnetic cell can lead to such magnetic field 112, have largely opposite
In the symmetrical characteristic (such as polarity and intensity) of specific axis (such as geometrical central axis).
On the other hand, magnetic cell can be arranged in this way, so that the combination in the magnetic field of magnetic cell can cause
At least one has the magnetic field 112 of the attribute relative to center line antisymmetry (anti-symmetric).For example, center line one
Magnetic cell on side can be positioned as north magnetic pole and be directed toward, and the correspondence magnetic cell on the center line other side can be arranged to southern magnetic
On pole is directed toward.It therefore, can be according to the magnetic for being considered suitable for providing the desired any way adjustment magnetic field 112 being matingly engaged
Attribute.For example, can by with magnetic field 112 can and another magnetic field cooperation interaction (for example, being from the attachment of another magnetic
System) mode arrange magnetic cell to modify the magnetic attribute in magnetic field 112.Cooperation interaction between two magnetic fields can lead to two
Object is by magnetic is attached each other in a manner of specific, accurate and is repeatable.
The attribute in magnetic field 112 can be stable.The stable attribute for being meant that magnetic field can be in a long period
Interior holding is basically unchanged.Therefore, it is possible to use there is the attribute of substantially constant (or approximately constant) on a long period,
Or any change by the offset magnetic cell of the corresponding change in another component in an at least component creates magnetic field
112 stable release.Magnetic cell can be fixed relative to other magnetic cells or at least substantially fixed configuration physical layout.Example
Such as, the polarity that each magnetic cell can be arranged respectively with fixed size and relative to each other with particular order, to provide magnetic
The desired attribute (shape, intensity, polarity etc.) of field 112.Therefore, according to the attribute of magnetic cell and property, the shape in magnetic field 112
It can keep substantially constant on a long period (the expection operation lifetime of such as electronic equipment 100).
However in some embodiments it is possible to changed by the magnetic or other physical attribute for modifying at least one magnetic cell
The attribute in magnetic field 112.When at least one magnetic cell has the magnetic attribute that can be modified (for example, polarity or field strength), gained magnetic
Field can also be modified.Therefore, at least one magnetic cell is characterized by with dynamic magnetic properties in certain embodiments.Dynamically
At least one magnetic attribute such as polarity can be modified by being meant that.In this way, the magnetic field properties in gained magnetic field also can change.
Gained magnetic field can change the magnetic characteristic in magnetic field 112 again, and the magnetic characteristic in magnetic field 112 can change how magnetic attachment system makes again
Obtain object magnetic attachment (alignment, orientation, placed in the middle etc.) each other.Electromagnet is the one of this magnetic cell that can modify magnetic attribute on demand
A example.Other examples include the malleable nonmagnetic substrate for injecting magnetic-doped object (such as magnetic iron ore).In this way, malleable
Matrix can be formed that the physical form of the property in the magnetic field generated by magnetic-doped object material can be influenced.
Turning now to the other aspects of magnetic attachment system, fixed attachment features part 110 may include one or more magnetic members
Part 116.When using multiple magnetic cells, the arrangement of multiple magnetic cells 116 can greatly change, and can set with another
Standby upper collaboration feature magnetic interaction.In one embodiment, multiple magnetic cells 116 associated with fixed character part 110 can
At least part for another equipment for being originally attached to electronic equipment 100 by means of equipment attachment features part 108 is auxiliarily fixed.
At least some of multiple magnetic cells 116 can have fixed size and polarity (along the row of simple magnet),
And some other magnetic cell in multiple magnetic cells 116 can have the magnetic attribute (such as electromagnet) that can change, while another
Some magnetic cells, which can have, provides the shape of specific magnetic characteristic.For example, at least one of multiple magnetic cells 116 can be positioned
For and be configured to (if necessary) with include that magnetic response circuit in another described equipment interacts.Therefore, magnetic response electricity
Road can respond the presence (or being not present) of the specific magnetic cell (multiple) of fixed character part 110.It is sensed above with Hall effect
Device 118 describes the example of magnetic response circuit.
It should be noted that should not be extended far with the magnetic field that magnetic cell 116 generates, to adversely affect electronic equipment
Magnetosensitive circuit (such as Hall effect transducer 118) in 100.Because since at least part magnetic field must prolong in z-direction
It stretches to be interacted with the magnetic active part of other equipment, so magnetic field, in general is not comprised in shell 102, this is especially important.
Therefore, it is necessary to extension of the magnetic field in { x, y } be limited, to avoid magnetosensitive circuit, such as Hall effect transducer 118 and compass
120。
In a particular embodiment, the magnetic cell of equipment attachment features part 108 is grouped into different magnetic regions.With this
The magnetic field of mode, these magnetic regions can be superimposed, to form magnetic field 112.Magnetic regions may include various magnetic cells, it
Can be disposed in the group indicated with magnetic cell 126 and 128.It, can be with by the way that magnetic cell to be grouped into different magnetic regions
Greatly enhancing magnetic attachment system provides the ability with the magnetic field of desired characteristic.Magnetic cell 126 and 128 can be interactively with each other
To form magnetic field 112.In one embodiment, interaction can take the magnetic attribute of each of magnetic cell 126 and 128
Combined form.In some cases, the arrangement of magnetic cell 126 and 128 can be related each other, in order to provide with desired properties
Magnetic field 112.For example, magnetic cell 126 and 128 can be arranged so relative to each other, so that magnetic field 112 is attached spy relative to magnetic
Levy the horizontal center line antisymmetry (or symmetrical) of part 108.In another embodiment, magnetic field 112 can be relative to attachment features
The vertical center line antisymmetry (or symmetrical) of part 108.In another embodiment, magnetic field 112 can be at horizontal and vertical two
Antisymmetry (or symmetrical) on direction.
Fig. 7 A shows the electronic equipment 100 close to the object 200 with magnetic attachment features part 202.The magnetic of object 200
Attachment features part 202 may include magnetic cell, and the magnetic cell, which respectively generates, interactively with each other to be formed to flock together
The independent magnetic field in gained magnetic field.Gained magnetic field, which can have, to be interacted with the magnetic field 112 of electronic equipment 100, so as to clear
, accurate and repeatable mode electronic equipment 100 and object 200 are attached together, without machanical fastener
The magnetic characteristic (such as, field strength and shape) of external auxiliary is not needed.It should be noted that magnetic field 208 can be about 2500 Gausses, and
When equipment attachment features part 108 be in it is inactive when, magnetic field 112 can be about 1400 Gausses.
Object 200 can take many forms, including attachment, peripheral hardware, electronic equipment etc..In one embodiment, object
200 can take the form of the electronic equipment of the route along electronic equipment 100.Therefore, electronic equipment 100 and object 200 can
To use equipment attachment features part 108 and magnetic attachment features part 202, magnetic is attached each other, to form coelectron system.The association
It can be the corresponding electronic element coordination with one another in electronic component and object 200 in electronic equipment 100 with electronic system, so as to
The system for executing the function that any one electronic equipment cannot all be individually performed.It in one embodiment, can be in electronic equipment
Information is transmitted between 100 and 200.
More specifically, magnetic attachment features part 202 can include at least magnetic cell 204 and 206, each can produce magnetic
, coordination with one another in order to provide magnetic field 208 (a part for illustrating only magnetic field 208) magnetic field.The attribute in magnetic field 208 can be with
Interaction based on each of multiple magnetic cells 204 and 206.In this way, magnetic field 208 can have based on multiple magnetic
The attribute of the physical layout of each of element 204 and 206, relative size and composition magnetic polarity.For example, 204 He of magnetic cell
206 can arrange along middle line, and with superposition in order to provide the magnetic attribute in the magnetic field 208 with desired properties.Object 200
Magnetic field 208 magnetic flux density B208The function that can be used as the distance x apart from magnetic cell 204 and 206 changes (that is, B=B208
(x))。
When object 200 takes such as form of the electronic equipment of electronic equipment 100, magnetic flux density B208Meet equation
(1).However, when object 200 takes the form of accessory device, it is close different from meeting the magnetic flux of electronic equipment 100 of equation (1)
Spend B112, the magnetic flux density B of accessory device 200208It can satisfy equation (2).
B208(x=x1+s)>BthresholdEquation (2)
Wherein s is thickness of the shell 212 at the 212a of side, and
x1It is internal spacing distance.
In this way, accessory device 200 can be interacted with 100 magnetic of electronic equipment, and can also leave electronic equipment
100, otherwise this is impossible.Therefore, accessory device 200 can be placed close to object 200 but need not abut electronic equipment 100
So that magnetic is attached each other in a manner of specific, accurate and is repeatable for electronic equipment 100 and object 200.
Other than magnetic attachment features part 202, accessory device 200 can also include that can be used for and fixed attachment features part
The magnetic attachment features part 216 of 110 interactions.Magnetic attachment features part 216 may include various magnetic driving components.Certain magnetic cells can be with
It takes and is arranged as and the form of the magnetic cell of the corresponding magnetic cell cooperation interaction in fixed attachment features part 110.Other magnetic cells
It substantially can be more passive, that is, they provide the machine completed with the magnetic circuit of the magnetic active member in fixed attachment features part 110
System.The example of magnetic passive device is ferromagnetic material, such as iron or steel, can magnetic field associated with actively providing magnetic cell
Interaction.In this way, ferromagnetic material can be interacted with magnetic field, to complete the passive device in attachment features part 216 and to consolidate
Determine the magnetic circuit between the active member in attachment features part 110.
Fig. 7 B, which is shown, can be used for providing the accessory device 200 supporting function and servicing for electronic equipment 100.By permitting
Perhaps there is the magnetic flux density B for meeting equation (2)208The a part in magnetic field 208 extend in region 214, equipment can be created
Magnetic attraction F between attachment features part 108 and attachment attachment features part 202net, wherein net magnetic attraction FnetMeet equation
(3a) and equation (3b).
Fnet=(Ltotal)·B2/μ0Equation (3a)
B/B0=f (xsep) equation (3b)
Wherein LtotalIt is the total surface area of magnetic cell
B is total magnetic flux density (B208+B112)
XsepIt is the spacing distance between magnetic cell,
B0It is the magnetic flux density at magnetic regions surface.
Net magnetic attraction FnetIt is since the interaction in magnetic field 208 and magnetic field 112 generates, attachment features part 202 can be used for swashing
Equipment attachment features part 108 living.In addition, when equipment attachment features part 108 is activated, magnetic flux density B112Now in moving type
State meets equation (4).
B112(x=xo+t)>Bthreshold,Equation (4)
Magnetic flux density B in region 214112This increase can cause between accessory device 200 and electronic equipment 100
Net magnetic attraction FnetDramatically increase.In addition, due to net magnetic attraction FnetWith total magnetic flux density B (B208+B112) change,
And magnetic flux density B generally can change (that is, equation 3 (b)) with spacing distance on the contrary, when electronic equipment 100 and attachment are set
Standby 200 is closer to each other, and spacing distance XsepDrop to and is consistent with the physical contact of electronic equipment 100 and accessory device 200
When limits value, net magnetic attraction FnetIncrease can be sharply increased in relatively short time quantum.This net magnetic attraction Fnet
Sharply increase and equipment can be caused to be pulled together rapidly, as seen in figure 7 c, this is referred to alternatively as " be attracted in place ", and Fig. 7 C is shown
Along the cooperative system 300 for electronic equipment 100 form that engagement surface 218 and 200 magnetic of accessory device are attached.It should be noted that
In a representative embodiment, the magnetic cell in equipment attachment features part 108 can be N52 type magnet, and attachment features
Magnetic cell in part 216 can be N53 type magnet.In addition, net magnetic attraction can be about 10 newton at least 20 newton,
Middle activation equipment attachment features part 108 may need about 3 newton.
All net magnetic attraction F for the magnetic cell that can be coupled according to all activesnetiSummation obtain and equipment 100 and set
Total net magnetic attraction F between standby 200 at engagement surface 218NET.In other words, total net magnetic attraction FNETMeet equation (5).
Wherein FnetiIt is the net magnetic attraction of each of n component component.In one embodiment, net magnetic attraction
FnetiGenerally perpendicular to the part that engagement surface 218 intersects with magnetic field 112 and magnetic field 208.
In order to ensure total magnetic attachment forces FNETIt is uniform, attachment along the engagement surface between equipment 100 and equipment 200
Spacing distance each of in feature 108 and 202 between corresponding magnetic cell is well controlled.It can be for example, by making magnetic
There is element the shape for meeting device shaped to control spacing distance well.For example, if equipment 100 has batten (bending)
The shell of shape can make the magnetic cell in equipment 100 have the shape for meeting the curved shape.In addition, magnetic cell can quilt
It is formed in this way, so that the magnetic vector of corresponding magnetic cell is in alignment with each other.In this way it is possible to desirably control
Make the size and Orientation of net magnetic attraction.
One of alignment magnetic vector is the result is that the direction of the net magnetic force between each magnetic cell can be controlled well.Separately
Outside, by the way that the spacing distance between corresponding magnetic cell is reduced to minimum, the net magnetic between each magnetic cell can be maximized
Gravitation Fneti.In addition, the spacing distance by keeping general uniform between each magnetic cell, can mention along engagement surface 218
For corresponding uniform magnetic attachment forces.In addition, engagement surface application can be orthogonal to by suitably adjusting corresponding magnetic vector
Fnet。
Other than minimizing the spacing distance between corresponding magnetic cell, corresponding magnetic member can also be increased using magnetic shunt path
Magnetic flux density between part.It can be placed on by the magnetic shunt path that magnetic active material such as iron or steel are formed on magnetic cell or attached
Closely, the effect that magnetic flux line is directed to desired orientation is realized.In this way, for example, this can deviate corresponding magnetic cell propagation
Magnetic flux line can be partly redirected to desired direction, such as towards the magnetic attachment area between equipment, to increase total magnetic
Flux density.Therefore, the obtainable magnetic flux density increased between magnetic cell can lead to dramatically increasing for net magnetic attraction.

A part.Specifically, attachment features part may include the magnetic cell 402 on the protrusion 404 for may be mounted to that shell 102.
Magnetic cell 402 can greatly change.For example, magnetic cell 402 can be on protrusion 404 by space layout in attachment
The array of the particular aspects of electronic equipment 100 is attached and is fixed at least part of equipment.For example, when accessory device is adopted
When taking fold form, it is magnetically fixed to electronic equipment 100 by fold to can be used magnetic cell 402, to cover display at least
A part.The size and shape of array can also greatly change.In the embodiment shown in Fig. 8 A, array is rectangle and has
There is the size of the signal portion including protrusion 404.
Fig. 8 B shows the multiple magnetic cells that can be integrated to by a part as attachment features part 216 in accessory device
410.Certain but not all in multiple magnetic cells 410 can correspond to magnetic cell 402, and be used for 200 magnetic of attachment
It is attached to electronic equipment 100.In another embodiment, all or most of magnetic cell can be used in multiple magnetic cells 410
The multiple portions of accessory device 200 are fixed together, to form the other support knots used in combination with electronic equipment 100
Structure.In one embodiment, magnetic cell 414 can be used for activating magnetosensitive circuit, such as Hall effect transducer 118.
Fig. 9 A-9C shows the representative magnetic attachment features part 500 of the embodiment according to description.Magnetic attachment features part 500
It can be for example corresponding to equipment attachment features part 108 shown in Fig. 6 and Fig. 7 A-7C.In inactive state, magnetic attachment features part
Magnetic cell in 500 can be positioned remote from shell 102, to minimize the magnetic field line propagated by shell 102.In another party
Face, in active state, magnetic cell can be mobile towards shell 102, to increase the number for the magnetic field line propagated by shell 102
Mesh, to meet equation (2).
The mobile mode of magnetic cell can greatly change.For example, magnetic cell can be rotated, rotates, translates, be slided.
In one example, magnetic cell, which can be positioned in, allows magnetic cell to slide into accordingly from the first position corresponding to inactive state
In in the channel of the second position of active state.
In the specific embodiment shown in Fig. 9 A-9C, attachment features part 500 may include have can be in a period
The upper magnetic cell 502 for keeping stable magnetic attribute.For example, it may be desired to which magnetic is attached attribute in the expected operation of electronic equipment 100
It keeps stablizing during service life.In this way, it will also keep stablizing by the magnetic field that the magnetic field interaction of each magnet is formed.Magnetic field
Stability can cause extremely reproducible attachment to handle.When electronic equipment 100 and other appropriately configured objects (such as need
Consistent pinpoint accessory device 200) when experience is multiple and duplicate attachment circulation (attachment/separated), it is this to weigh
Renaturation is particularly useful.
In the representative embodiment shown in, magnetic cell 502 can take many forms.For example, magnetic cell 502 can be adopted
It takes with the shape of multiple magnets with stable magnetic attribute (such as polarity and intrinsic magnetic intensity) of particular order and deployment arrangements
Formula.However, in order to magnetic attachment features part 500 be in it is inactive when meet equation (1), magnetic cell 502 must with outside shell 102
At least keep at a distance x=(x in portion0+t).In other words, in order to meet equation (1), the size of equipment attachment features part 500 must be extremely
The magnetic attribute and physical layout of magnetic cell 502 are considered less.
Therefore, magnetic cell 502, which can be attached to, is arranged as playing retentivity FretainHolding mechanism 504.Retentivity
FretainIt can be used for being maintained at magnetic cell 502 in equipment attachment features part 500 at a position, thus when equipment attachment is special
Sign part 500 leads to have little or no flux leakage (that is, meeting equation except electronic equipment 100 when being in inactive
(1)).In one embodiment, holding mechanism 504, which can be taken, is arranged as providing retentivity F according to equation (6)retainSpring
Form:
Fretain=k △ x equation (6)
Wherein k is to maintain the spring constant of mechanism 504, and
Δ x is the displacement from equilbrium position.
For example, Fig. 9 B shows the representative magnetic attachment features part 500 of active state.Pass through appropriately configured magnetic cell 502
With the magnetic cell in attachment attachment features part 204, the magnetic field of the magnetic field of magnetic cell 502 and the generation of attachment attachment features part 204
The interaction of gained magnetic can create at least with equally big net magnetic attraction needed for activation magnetic attachment features part 500.In other words, net magnetic
Attraction can at least have the activating force F for meeting equation (7)actQuantity, to overcome retentivity FretainSo that magnetic is first
Part 502 is just moved to moving position (that is, x=x from passive position (that is, x=0)0)。
Fact≥Fretain(Δ x=xo) equation (7)
However, only generating with attached with another magnetic in the magnetic field of the attribute of the magnetic field properties " matching " of magnetic cell 502
Magnetic attachment features part 500 can be activated by connecing feature.Therefore, as shown in Fig. 9 C, positioned at 102 outer surface of shell with magnetic master
The presence for the object 506 that dynamic material (such as steel) is formed is (that is, x=x0+ t) magnetic attachment features part 500 cannot be activated.More specifically
Ground, in one embodiment, the net magnetic attraction generated between object 506 and magnetic attachment features part 500 are less than 2NT, and swash
Vigor FACTIt can be about 3NT.
More specifically, being generated between magnetic cell 502 and object 506 to be changed into active state from inactive state
Magnetic force have to be larger than activating force FACT.However, due to the magnetic in the magnetic field that 102 outer surface of shell is generated with magnetic cell 502
Flux density is less than Bthreshold, any magnetic force generated between object 506 and magnetic cell 502 is significantly less than Fretain, and because
This is unsatisfactory for equation (7).Therefore, magnetic cell 502 is maintained at the position of about x=0, and magnetic attachment features part 500 cannot be through
Go through the transformation from inactive state to active state.
It should be appreciated that spring can greatly change.For example, it can change according to mobile type.Example include tense,
Compression, torsion, overturning etc..In a kind of specific implementation, leaf spring is used.
It shall also be noted that in certain embodiments, magnetic cell 502 can be fixed in a manner of not needing spring.At these
Embodiment, although equation (1) may be unsatisfactory for, it can be a kind of actual arrangement.
Figure 10 shows the embodiment of equipment attachment features part 600 according to an embodiment of the invention.Attachment features
Part 600 can correspond to the element 208 in Fig. 6 and Fig. 7 A-7C.In addition to replacing single mechanism, using multiple mechanisms and more
Except a pair of of the mechanism for using to body magnetic cell 602 and 604 form of magnetic cell, which is similar to real shown in Fig. 9 A-9C
Apply example.Specifically, Figure 10 shows the equipment attachment features part 600 of active state.More specifically, being attached to magnetic cell 602
Spring 606 and the respective extended distance Δ x of spring 608 for being attached to magnetic cell 604.
In this system, the two mechanisms combines are to form magnetic field.They can be individually moved or they can be connected
It is connected together so as to mobile as a unit.Spring force and magnetic force can change.For example, system can be it is symmetrical or not right
Claim.The arrangement of magnetic cell can be similar or different.It equally can be symmetrical or asymmetric.The configuration can take

Figure 11 A-11B is shown according to one embodiment, the equipment attachment features part of 700 form of equipment attachment features part
108 specific implementation.Equipment attachment features part can correspond to element 108 shown in Fig. 6 and Fig. 7 A-7C.In some cases,
Can spring 606 and 608 as shown in connection with fig. 10 use equipment attachment features part 700.As shown in Figure 11 A, equipment attachment features
Part 700.Specifically, equipment attachment features part 700 is shown as having the magnetic group that can be closed inside the shell in inactive state
The magnetic cell of 702 form of part.In this way, the holding mechanism (not shown) for being attached to magnetic assembly 702 can play related guarantor
Holding force Fretain.Retentivity FretainIt can be used for for magnetic assembly 702 being maintained at and be in inactive with equipment attachment features part 700
The position that state (that is, meeting equation (1)) is consistent.
Each magnetic assembly 702 may include independent magnet.In the described embodiment, independent magnet can be disposed in magnet pole

Degree is formed.In other words, magnetic pole sequence may be expressed as such as {+1 ,+1, -1 ,+1, -1 ,+1, -1, -1 }.For this particular case
Son, "+1 " indicate direction and the intensity of magnet.Therefore, positive sign "+" can indicate that corresponding magnet is aligned with specific direction
Magnetic vector, negative sign "-" can indicate the magnetic vector of opposite direction, and " 1 " indicates the intensity of a unit magnet.
When multiple magnets of identical polar are placed one by one, each of multiple magnets can be combined
Magnetic field, so that multiple magnets can be deemed to be equivalent to single magnet, which has the composite attribute of the multiple magnet.
For example, indicating that the coding magnetic order column {+1 ,+1, -1 ,+1, -1 ,+1, -1, -1 } of 8 independent magnets can be deemed to be equivalent to embody
{+2, -1 ,+1, -1 ,+1, -2 } are arranged for the coding magnetic order of 6 independent magnet arrays.In one embodiment, first and last position
The magnet set can possess magnetic intensity identical with other magnets in array, but twice its is correspondingly sized.In another party
Face, first and rearmost position magnet can with other magnets have about the same size, but have twice other magnetic
The magnetic intensity of body.In any case, the identity property of magnetic attribute can provide more compact coding magnetic order column.Lesser size can
Help to reduce weight, and keeps valuable inner space quantity needed for accommodating magnetic attachment features part.In addition, due to magnetic
Flux density is directly related with the area that magnetic field line is propagated by it, when given magnetic flux is reduced by the area that it is propagated, gained
Magnetic flux density increase.
In one embodiment, magnetic assembly 702 may include the independent magnet for being respectively provided with relative size 2L, 1L and 1L
712a, 712b and 712c, wherein " L " indicates unit length.It should be appreciated that it is as discussed above, with relative size " 2L "
Magnet can be embodied in single magnet with " 2L " physical length, two be close to respectively there is length " 1L " and have
The magnet for the magnetic pole being in alignment with each other, magnetic intensity with twice other magnets unit length L magnet.Therefore, for this
The rest part of discussion can indicate unit length for term 2L and 1L, " L ", and the relative intensity of magnet can be by with phase
Associated digital representation.For example, can be deemed to be equivalent to have with the magnet of magnetic intensity " 1 " and length " 2L " relatively relatively strong
